actually I am running an exe file within my Matlab code, which helps me in calculating some part of my work, this DOS.exe will run and ask question .. like ('what parameter do you want input?') you need to input and then click ENTER,, but I am going to make it GUI where no command window to input and click ENTER,, so input some how I ll code but don't know how to ask Matlab to press ENTER ,, I hope you understand what I mean — Eng.RSMY, Aug 20 '17 at 04:04

I have this generic solution, based on undocumented matlab. It enables to press any button based on a string input (e.g. '0') by searching through a string of possible buttons to press. Watch out, this will also be pressed outside of the Matlab environment.
